NAME

     glutSpecialUpFunc -- Sets the special key release callback for the current window

LIBRARY

     OpenGLUT - input

SYNOPSIS

     #include <openglut.h>

     void
     glutSpecialUpFunc(void( *callback )( int key, int x, int y ));

PARAMETERS

      callback	   Client hook for special key releases.

DESCRIPTION

     This function provides a way to detect the release of a keyboard  key.   The keys are reported exactly as with glutSpecialFunc(), save that
     the  callback  registered via this function is used to report the event.

     This callback is bound to the  current window  .

CAVEATS

     Windows created via glutCreateMenuWindow() always cascade keyboard and mouse events to their parent.

NAME

       glutSpecialUpFunc - sets the special keyboard up (key release) callback for the current window.

SYNTAX

       void glutSpecialUpFunc(void (*func)(int key, int x, int y));

ARGUMENTS

       func	 The new special callback function.

DESCRIPTION

       glutSpecialUpFunc sets the special keyboard up (key release) callback for the current window. The special keyboard up callback is triggered
       when keyboard function or directional keys are released. The key callback parameter is a GLUT_KEY_* constant for the special  key  pressed.
       The  x  and y callback parameters indicate the mouse in window relative coordinates when the key was pressed. When a new window is created,
       no special up callback is initially registered and special key releases in the window are ignored.  Passing NULL to glutSpecialUpFunc  dis-
       ables the generation of special up callbacks.

       During  a  special  up callback, glutGetModifiers may be called to determine the state of modifier keys when the key release generating the
       callback occurred.

       To avoid the reporting of key release/press pairs due to auto repeat, use glutIgnoreKeyRepeat to ignore auto repeated keystrokes.

       An implementation should do its best to provide ways to generate all the GLUT_KEY_* special keys. The available GLUT_KEY_* values are:

       GLUT_KEY_F1
	       F1 function key.

       GLUT_KEY_F2
	       F2 function key.

       GLUT_KEY_F3
	       F3 function key.

       GLUT_KEY_F4
	       F4 function key.

       GLUT_KEY_F5
	       F5 function key.

       GLUT_KEY_F6
	       F6 function key.

       GLUT_KEY_F7
	       F7 function key.

       GLUT_KEY_F8
	       F8 function key.

       GLUT_KEY_F9
	       F9 function key.

       GLUT_KEY_F10
	       F10 function key.

       GLUT_KEY_F11
	       F11 function key.

       GLUT_KEY_F12
	       F12 function key.

       GLUT_KEY_LEFT
	       Left directional key.

       GLUT_KEY_UP
	       Up directional key.

       GLUT_KEY_RIGHT
	       Right directional key.

       GLUT_KEY_DOWN
	       Down directional key.

       GLUT_KEY_PAGE_UP
	       Page up directional key.

       GLUT_KEY_PAGE_DOWN
	       Page down directional key.

       GLUT_KEY_HOME
	       Home directional key.

       GLUT_KEY_END
	       End directional key.

       GLUT_KEY_INSERT
	       Inset directional key.

       Note that the escape, backspace, and delete keys are generated as an ASCII character.
